The chromenes, coumarines, pyrido-pyrimidine and quinazoline cores possesses a vast number of biological activities such as anticancer, anti-malarial, anti-microbial, anti-fungal, anti-tubercular activities and the conventional classical synthetic methods have harsh conditions having multistep process. Currently, researchers are in search of new methodology to eliminate the use of chemicals, solvents and catalysts, which are hazardous to human health as well as to environment. This review provides a concise overview of new dimensions of one pot multi-component synthetic approaches in designing chromenes, coumarines, pyrido-pyrimidine and quinazoline scaffolds. This review will give more scientific ideas to synthesis a variety of heterocyclic moieties in a new synthetic way following the one-pot multi-component method.
